Actor Leonardo DiCaprio has turned over an Oscar won by Marlon Brando to U.S. investigators probing alleged money laundering by a state-owned Malaysian investment fund, his representatives said on Thursday.

DiCaprio has also initiated the return of other, unidentified items that the actor said he accepted as gifts for a charity auction and which originated from people connected to the 1MDB wealth fund, they said in a statement.

In July, Hollywood production company Red Granite was accused in a U.S. civil lawsuit of using $100 million that prosecutors said had been diverted from the 1MDB fund to finance DiCaprio’s 2013 film “The Wolf of Wall Street,” in which he starred.

DiCaprio said in October he was cooperating with the probe and would return any gifts or donations if they were found to have come from questionable sources.
